The work flow of the data center control system provided by the invention is described in the data center control method.
As shown in fig. 2, the data center control method includes the steps of:
s100, detecting temperature values in a cold channel in real time by a plurality of temperature sensors, and respectively sending the temperature values to a controller;
s200, the controller receives temperature values respectively sent by the temperature sensors and continuously calculates an average temperature value in the cold channel;
s300, judging whether the average temperature value is larger than the sum of the temperature set value and the temperature set difference value or not by the controller, and starting a first indoor unit if the average temperature value is larger than the sum of the temperature set value and the temperature set difference value;
s400, after the first preset time interval is over, the controller judges whether the current average temperature value is larger than the sum of the temperature set value and the temperature set difference value or not, if so, the second indoor unit is started, and the like, and the controller repeats the judging process until the calculated average temperature value is smaller than or equal to the sum of the temperature set value and the temperature set difference value.
That is, the specific loading control logic of the indoor unit firstly detects the average temperature value T of the cold channel1And is related to the temperature set point T0And (4) judging the + temperature deviation value (loading value) delta T. When the average temperature value T of the cold channel1＞（T0+ Δ T), the air conditioner will have a loading demand, the indoor unit starts loading from the first indoor unit, and the first indoor unit refrigeration valve is opened; if the average temperature value of the cold channel is still larger than (T)0+ Δ T), after waiting for a first preset time interval (secondary on delay time), the second indoor unit is loaded again, and the refrigeration valve of the second indoor unit is opened; when the loading quantity of the indoor unit meets the starting pressure (P) of the compressorStarting up+ pressure deviation Δ P), the compressor will start at a low frequency hhow, starting the refrigeration operation.
The indoor unit controller monitors the temperature trend of the cold channel in real time, when the indoor unit is detected to be horizontal or upward, the indoor unit is allowed to continue to be loaded, otherwise, the indoor unit is not loaded, and the number of the started indoor units is kept to execute the refrigerating operation.
Further, when the average temperature value is greater than or equal to the temperature set value and less than or equal to the sum of the temperature set value and the temperature set difference value, the controller performs linear adjustment of the indoor fan output wind speed according to the continuously calculated average temperature value, and the adjustment range is from the lowest set rotating speed to the highest set rotating speed (the default lowest set rotating speed is 50%, and the default best set rotating speed is 100%).
At the moment, the running frequency of the compressor is between the lowest frequency and the highest frequency, linear regulation is synchronously executed (the highest frequency value and the lowest frequency value of the running of the compressor can be set), and the refrigerating capacity of the air conditioning system is in the output process of steady-state regulation by real-time output matching with the rotating speed of the indoor fan, so that the best matching between the refrigerating capacity and the heat load of the server is achieved, and the optimal refrigerating state of the air conditioning system is realized.
Real-time output rotating speed S = S1+ ((S2-S1)/delta T) of indoor fan of air conditioner1-T0)), thereby realizing stepless output of the refrigerating capacity of each indoor unit; wherein S is the output rotating speed of the indoor fan, S1For minimum set speed of indoor fan, S2For the maximum set speed of the indoor fan, Δ T is the temperature set difference, T1Is the average temperature value, T, in the cold aisle0Is the temperature set point.
In addition, the method further comprises the following steps after the step S400:
the controller judges whether the average temperature value is smaller than a temperature set value and is in a descending trend;
if yes, the controller controls one indoor unit to stop running;
after a second preset time interval, the controller judges whether the average temperature value is smaller than the temperature set value and is in a descending trend again;
if so, the controller controls one indoor unit to stop running again, and so on until the currently running compressor reaches the stop condition to stop running.
That is, when the average temperature Taverage within the data center cold aisle falls to the temperature set point Tset0And when the output rotating speed of all the indoor fans in the running state is reduced to the lower limit value, the output of the refrigerating capacity is minimum.
The main controller detects the descending trend of the temperature of the cold channel in real time, and if the temperature of the cold channel is lower than T0And the temperature is the descending trend, the air conditioner is at TDelay of machine halt(can be set by oneself, defaults 20 s), close a indoor machine refrigeration valve; if the temperature of the cold channel continues to decline, the air conditioner in operation delays (T)Delay of machine haltThe number of the closed air conditioners in the current shutdown process), the other indoor unit refrigeration valve is continuously closed. The closed indoor unit closes a refrigerating valve of the indoor unit, and the rotating speed of a fan is regulated to the rotating speed in a standby state (the rotating speed in the standby state can be set, and the default value is 40%); if the temperature rises, the indoor unit refrigeration valve will not be closed continuously; if the temperature trend is continuously reduced, the closing is continued after a delay until the stop pressure value P of the compressor is reachedShutdownWhen the compressor stops refrigerating operation, all indoor fans execute the rotation speed in the standby stateAnd (6) outputting.
The outdoor unit of the air conditioning control system is provided with an outdoor unit controller, and the outdoor unit controller is communicated with the indoor unit controller in real time through RS485, as shown in figure 1.
When the running frequency of the large-cooling-capacity compressor of the second outdoor unit is increased to the highest frequency, the running mode is switched to the power frequency mode, and at the moment, the frequency converter does not output an instruction.
If the system pressure continuously rises and the temperature of the cold channel still cannot drop, the small cold capacity compressor of the first outdoor unit is started again, the first outdoor unit preferentially operates in a frequency conversion mode, and the frequency output is adjusted in real time until the temperature of the cold channel of the data center is stable.
Through the multi-stage output adjustment of the refrigerating capacity of the compressor, the refrigerating capacity is reasonably matched and adjusted with the stepless output of the rotating speed of the fan unit of the indoor unit and the load increase and load decrease of the indoor unit, and finally the temperature field stability of the data center is achieved.
